Double thermoelectric power factor of a 2D electron system.

ABSTRACT: Two-dimensional electron systems have attracted attention as thermoelectric materials, which can directly convert waste heat into electricity. It has been theoretically predicted that thermoelectric power factor can be largely enhanced when the two-dimensional electron layer is far narrower than the de Broglie wavelength. Although many studies have been made, the effectiveness has not been experimentally clarified thus far. Here we experimentally clarify that an enhanced two-dimensionality is efficient to enhance thermoelectric power factor. We fabricated superlattices of [N unit cell SrTi_1-xNb _x O₃|11 unit cell SrTiO₃]₁₀-there are two different de Broglie wavelength in the SrTi_1-xNb _x O₃ system. The ma
